Boost Voltage Charging Controller,Multi-stage Charge Algorithm,Flexible Application MPPT Solar Controller
1 .Function
1) Boost Voltage Charging Controller
Designed for scenarios where the photovoltaic input voltage is lower than the battery voltage, this controller effectively boosts the voltage to match the battery's charging requirements. It overcomes limitations caused by insufficient voltage from a single photovoltaic panel, ensuring reliable battery charging.
2) Integrated charge presets
Integrated charge presets combined with adaptive charge logic are well suited for most common battery types, such as LiFePO4, Gel and flooded lead-acid.
3) Flexible Application
Compatible with 24V/36V/48V/60V/72V system voltage.
4) Multi-stage charge algorithm
The multi-stage charge algorithm is specifically engineered to optimize each recharge cycle and charge maintenance over extended periods.
5) Adaptive boost charge
Adaptive boost charge monitors the battery's response during initial charging and intelligently determines the appropriate boost charge duration for each individual charge cycle. This ensures that the battery is fully recharged regardless of the discharge level or capacity and avoids excessive time at the elevated boost charging voltage (that can accelerate battery aging).
6) Durable and safe
i. Protection against overheating: When the equipment temperature exceeds 85℃, the control automatically stops charging. Resume charging when the equipment temperature is 75 ℃.
ii. Protection against output short circuit.
iii. Protection against reverse polarity connection: No damage to the controller will result, when polarity is reversed. And the controller will not work.
iv. Limit the maximum charging current. Protect battery performance and prolong battery life.
7) Silent operation
Almost silent operation since there is no cooling fan or moving parts, cooling is via natural convection.
8) Lithium battery activation
Compatible with Li-ion (LiFePO₄) batteries; when the battery type parameter is set to Lithium battery the charge cycle settings are altered to suit. Moreover, when the connected lithium battery is in a protected state, the controller will activate the lithium battery using the energy from the solar panel with a current that does not exceed the lithium battery's protection voltage and current range.
Warning: Do not charge Li-ion batteries if the battery temperature is below 0°C.
